SPECIFICATION forming part of Letters Patent No. 636,314, dated November7, 1899.

Application filed August l, 1899. Serial No. 725,778. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, AUGUST WILHELM BILL- MAN, manufacturer, of 35 MasterSamuelsgatan, Stockholm, Sweden, have invented Improvements inHose-Couplings, of which the following is a specification.

This invention relates to a modification of the hose-coupling describedin Letters Patent No. 590,956, and has for its objectto simplify saidcoupling and to provide a better protection for the parts actuating thecouplinglatches. The coupling described in the aforesaid patent consistsof two lugs projecting axially diametrically opposite each other fromthe head end of each section or coupling-half, there being in one ofsaid lugs a latch movable about tangentially to the circumference of thecoupling sleeve or section, against the rear end of which latch bearsone end of a bell-crank lever fulcrumed on a shaft or pin parallel tothe axis of the sleeve, while its other end vis located in an opening inthe sleeve and is forced outward by an elastic ring inserted in themouth of the aforesaid sleeve, and the other lug is provided with arecess into which the latch of the other coupling-half can snap when thetwo halves are pushed together. According to the present invention thebell-crank mentioned is replaced by a spring and the couplingconsequently obtaining a smaller number of projecting parts is not soeasily injured or brought out o f order.

In the accompanying drawings a symmetrical hose-coupling arrangedaccording to the present invention is shown in Figure l in a side Viewwith the two halves or sections coupled together. In Fig. 2 is shown oneof the coupling-halves viewed from one end, and in Fig. 3, partially insection, one of the coupling-halves with the coupling-latch intheposition occupied at the moment when the sections of the coupling arebeing united or disconnected.

a. are the coupling .halves or sections with their lugs b c, and d isthe latch, movable in one of the latter about tangentially orconcentrically to the circumference of the section. According to thepresent invention the said latch is not, as in my Patent No. 590,956,operated by a rocking lever, but directly by means of a spring, whichmay be a spiral spring f, located in the lug, as illustrated in thedrawings, or any other spring protected in a similar manner and actingto push the `latch outward, as shown in Fig. 2. The latch has a handlec, by means of Which it may be Withdrawn.

g is an aperture in the lug c, into which the latch d, belonging to theother coupling-half, will snap when the ends of the two sections arepushed together.

In order that the latches mayfreadily engage with the correspondingapertures as the sections of the coupling are united, the ends of thelatches should be slanted. In disconnecting the sections the handles eof the two latches are pulled, the latter being consequentlywithdrawn'out of their engagement, so that the sections of the couplingmay be pulled apart.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the saine is to be performed, I declarethat what I claim is- An improved symmetrical hose-coupling providedwith lugs b, c projecting axially diametrically opposite each other fromthe head end of each coupling half or section a, and in one of said lugshaving a latch d movable about peripherally or concentrically to thecircumference of the coupling sleeve or section and actuated by a springf pushing the latch outward so as to cause it, when the coupling-halvesare forced together, to snap into an aperture g arranged in thecorresponding lug c of the other coupling half or section.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

AUGUST WILHELM BILLMAN.
